NEC memory to replace flash and RAM

The battle for the future memory rages between NEC and the dance with the "CAM", alias Content Addressable Memory. The Japanese company with promises that this memory will be possible to replace the conventional RAM and flash memory. The operation is based on MRAM (Magnetic RAM) with a "magnetic wall" that moves and can set the data area, as shown in the chart.

Memory is indeed as fast as RAM with an access time of 5 nanoseconds - flash memory is around a millisecond - but is able to keep the information without being replenished, such as flash memory. The chips currently produced are only 16 kilobits and etched in 90 nm, which is far from current standards, but they could eventually replace flash memory and RAM, which would provide computers able to start immediately.
